Received free sample shipping and handling paid by credit card, product did nothing for me , 3 weeks later received unsolicted and unwanted month's supply. Calling phone# given for retun has automatic sales pitch after 30 minutes gave up, how stupid to set on the phone for that. No credit given without so called RMA cannot return product. Tried several more times to get someone on the phone to no avail. Cancelled credit card they did get for 60$ or so.
